What are bifold doors?
Bifold doors are panels hinged together that fold back to one or both sides, opening almost the whole width.
We fitted two 5m-wide heritage bifolds on our Harrogate stone property and a five-panel bifold on the Doncaster new build.

| Space needed | None beyond the track | Folded stack at the side |
| Best for | Views and light, wide openings | Opening a room to the garden |
Questions
When are bifolds the better choice?
When being able to open almost the full width matters more than having the largest possible panes — for example, a kitchen opening onto a terrace.
How much do bifold doors cost?
There is no meaningful fixed price. Cost depends on size, configuration, glass, colour, hardware, access and the complexity of installation. We provide a written quotation against an agreed specification, typically within 48 hours of having the details we need.
